How should multiple OSPF areas be designed when deployed on a classic three-layer (core/distribution/access) network hierarchy?

The OSPF flooding domain boundary should be at the edge of the core layer.

The OSPF flooding domain boundary should be within the distribution layer.

A company plans to establish a new network using Cisco Catalyst switches for its multicast applications. What is the disadvantage when two multicast applications are using the multicast IP addresses 234.17.4.5 and 234.145.4.5 inside the same network?

Multicast packets from both applications are flooded to all Layer 2 ports in a segment where a multicast receiver is located.

Multicast packets from both applications are flooded to ports where one multicast receiver from one application is located.

Only one multicast stream is received at the port where the receivers from both applications are located.

Both multicast senders will always receive the multicast packets from the other multicast application.

The routers doing PIM-SM cannot distinguish between the two multicast applications.

Answer: B
